SPECIFICATION forming part of Letters Patent No. 637,063, dated November 14, 1899.

Application filed January 18, 1899. Serial No. 702,579. (No model.)

To all whom it may-concern:

Be it known that I, CARL FREDRIK ANDER SON, a citizen of the United States, and a resident of West New York, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Adjustable Saw-Sets, of which the following is a specification.

The object of the present invention is to provide a universally-adjustable saw-set so' arranged that it can be readily used and easily adjusted for any kind of saw.

The invention is preferably made with the jaws having suitable handles, and each jaw has near its end a vertically-movable hearingpiece, with an inclined side for the saw-blade, and also below this bearing-piece a laterallymovable finger, with an inclined face for the saw-tooth corresponding with the inclined side of the bearing-piece. There are also ad justing-screws on the side and top of each jaw, so as to adapt the instrument for use with any saw, and on each side of the jaw, directly beneath the line of saw-teeth, is a vertically-adj ustable guide-finger to hold the saw in line, all of which will now be set forth in detail.

In the accompanying drawings, Figure 1 is a side view of my adjustable saw-set. Fig. 2 is an edge view of same; Fig. 3, a view of the inner face of one of the jaws; Fig. 4, a perspective view of the bearing-piece for the blade of the saw, and Fig. 5 a perspective View of the finger for engaging with the tooth of the saw. p

In constructing my invention I prepare two parts A B, which are hinged together at 0,

each part having a handle D, and on the opposite ends of the hinged portion a jaw E. The jaws are similarly equipped, so that the description of one will serve for both. The jaws are each cut away on theirinner sides, so as to provide a space between them when the handles are together, and at the end of each is a longitudinal slot F, closed at the end by a cap G. In this slot is placed abearing-piece H, which has a wing I, resting within the slot F and adjustably held therein by a thumb-screw J on the outside of the jaw. On the opposite side of this piece H is an inclined bearing-face K, and a portion of this face is cut away, as shown at L, so that when the two jaws are placed together the inclined face K on the bearing-piece of one jaw will be directly opposite the cut-away portion L on the bearing-piece of the other jaw. Below the slot F is another slot M, transversely across the jaw, and this slot on the inside of the jaw has its sides gained, as at N. In this'gained slot I place a finger O, which projects upwardly parallel with the side of the jaw, being cut away, as at P, so that the reduced portion of the bearing-piece H will not rest beneath or behind the finger. The end of the finger is A-shaped, and on the side facing the jaw is a projection P, having an inclined face similar to the inclined surface on the bearing-piece H. At the base of this finger is a block Q, which slides in the gain N, and a thumb-screw B through this slot serves to adjust the finger when desired.

The cap G has two thumb-screws, the first, S, being vertically disposed, so that it enters the vertical slot..F in order to reinforce the screw J, and the other, T, which passes horizontally through one end of the cap, is designed to rest against the saw-blade, its office being to hold the saw-blade vertically or parallelwit-h the sides of the jaws when the latter are forced against the blade in the proc* ess of setting a tooth.

On each side of the jaws is a finger U, slotted at its lower end, as shown at V, and held by a set-screw W, and having at its upper end a head X, and on this head the teeth of the saw rest while the setting operation is going on.

The operation of the saw-set is very simple.

When it is desired to adjust it for a saw, the

blade-bearing pieces are so adjusted in relation to the ends of the fingers O that a sufficient portion of the tooth is embraced by the fingers, after which the fingers O'are moved together, so that the finger of one jaw will engage with a tooth which is to be bent or set in one direction and the finger on the other jaw will engage with and bend the next tooth in the opposite direction. Thus the set is so ar ranged that two teeth are set at one operation, and in doing so no more pressure is required than in setting one tooth, because as the teeth then set are contiguous to each other one reacts against the other, thus assuring a regular and uniform settingof all the teeth.

More or less set may be provided for in two waysfirst, by the set-screws T through the cap, and, second, by the vertical adjustment of the slotted fingers U in the sides of the aw.

What I claim as new is l. The combination of two jaws each having a longitudinally-adjustable bearingpiece for a saw-blade, provided with an inclined surface and a laterally-adjustable finger below said bearing-piece and partially resting -thereon, and a horizontal adjustingscrew through the head of each jaw for holding the saw parallel with the jaws and giving greater or less set to the saw, substantially as set forth.

2. The combination of two jaws each havtically-adjustable finger on the side of each jaw for holding the saw in position, substantially as set forth.
